For reliable VoIP calls to be routed via this homeserver, you MUST configure
a TURN server. See `<docs/turn-howto.rst>`_ for details.
IPv6
----
As of Synapse 0.19 we finally support IPv6, many thanks to @kyrias and @glyph
for providing PR #1696.
However, for federation to work on hosts with IPv6 DNS servers you **must**
be running Twisted 17.1.0 or later - see https://github.com/matrix-org/synapse/issues/1002
for details. We can't make Synapse depend on Twisted 17.1 by default
yet as it will break most older distributions (see https://github.com/matrix-org/synapse/pull/1909)
so if you are using operating system dependencies you'll have to install your
own Twisted 17.1 package via pip or backports etc.
If you're running in a virtualenv then pip should have installed the newest
Twisted automatically, but if your virtualenv is old you will need to manually
upgrade to a newer Twisted dependency via:
pip install Twisted>=17.1.0

Query Account
=============
This API returns information about a specific user account.
The api is::
GET /_matrix/client/r0/admin/whois/<user_id>
including an ``access_token`` of a server admin.
It returns a JSON body like the following:
.. code:: json
{
"user_id": "<user_id>",
"devices": {
"": {
"sessions": [
{
"connections": [
{
"ip": "1.2.3.4",
"last_seen": 1417222374433,
"user_agent": "Mozilla/5.0 ..."
},
{
"ip": "1.2.3.10",
"last_seen": 1417222374500,
"user_agent": "Dalvik/2.1.0 ..."
}
]
}
]
}
}
}
``last_seen`` is measured in milliseconds since the Unix epoch.
Deactivate Account
==================
This API deactivates an account. It removes active access tokens, resets the
password, and deletes third-party IDs (to prevent the user requesting a
password reset).
The api is::
POST /_matrix/client/r0/admin/deactivate/<user_id>
including an ``access_token`` of a server admin, and an empty request body.
Reset password
==============
Changes the password of another user.
The api is::
POST /_matrix/client/r0/admin/reset_password/<user_id>
with a body of:
.. code:: json
{
"new_password": "<secret>"
}
including an ``access_token`` of a server admin.
